Commercial Projects

Shelter Holdings

(Updated as of September 2021) Developer Shelter Holdings owns the L-shaped property located along 9th Avenue Northeast from Northeast High Street to Northeast Discovery Drive and from Northeast Discovery Drive to 5th Place Northeast. Since 2014, Shelter Holdings has desired to develop this property with uses it feels will serve our community. In 2017, Shelter Holdings began subdividing the 1.8 million square foot property zoned retail/commercial and pursued approvals for several development proposals that complied with the Issaquah Highlands Development Agreement.

The proposals included:

  • Retail: Pedestrian-oriented retail development similar in scale to the existing Grand Ridge Plaza, to include several restaurants, an entertainment facility, specialty grocer, pharmacy, daycare, and other daily goods and services. The proposal consists of 107,000 square feet of building area distributed among 11 buildings on five lots, with off-street surface parking for about 545 stalls. The buildings would primarily be single-story retail with opportunities for an additional 13,000 square feet of second-story retail, restaurants, or deck space to take advantage of views from the site. This second-story option would increase the total building area to 120,000 square feet.
  • Medical Office: A medical office building (sized 88,000 square feet) to complement and support the existing Swedish Hospital and Proliance medical facilities, including 391 parking stalls.
  • Self-Storage: A 108,385 square feet, four-story self-storage facility with three stories above grade and one story below grade.
  • Corner of 9th Avenue Northeast and Northeast Discovery Drive: The site includes a proposal for 120,000 gross square feet of office space, an 18,000 gross square feet fitness center, and 5,000 gross square feet of retail to complement and support the existing community, including Swedish Hospital and Proliance medical facilities, and the previously mentioned medical office building. The site is adjacent to Northeast Discovery Drive, approximately 154,030 square feet (3.54 acres), with approximately 291 parking stalls (including 17 on-street). The building would be sited to the southeastern portion of the site to activate the corner of 9th Ave Northeast and Northeast Discovery Drive. According to the city of Issaquah, this portion of the project only went through a pre-application process and Shelter Holdings did not submit a Site Development Permit. The city has not denied development of this parcel.

The city denied Shelter Holdings’ applications because they do not comply with the new regulations adopted after termination of the Issaquah Highlands Development Agreement. Shelter Holdings argues it submitted its applications before termination of the development agreement, and the new regulations should not apply to their plans for the parcel.

The current Issaquah Highlands development regulations adopted by the city in 2018 require a minimum of over 900,000 square feet of dense commercial development. In a statement to Highlands Council, Shelter Holdings said, “the type of large-scale office buildings that the regulations require is not economically feasible in Issaquah Highlands.” The dispute remains in litigation.

Block 20:

(Updated as of September 2021) In August, hotel developer Sycan sold the former City Surf location to BML Development Corporation. According to the company’s real estate broker, BML has “hired consultants to analyze the property and make recommendations for the best use of the land.” This 90,000 square foot parcel, located behind Dick’s Sporting Goods at the corner of 10th Avenue Northeast and Northeast Falls Drive, is zoned for retail/commercial use.

Swedish Hospital:

(Updated as of September 2021) Swedish Issaquah has a development agreement with the city of Issaquah that runs through 2033. The project contains approximately 28 acres and 1,077,000 gross square feet; about 538,000 square feet are complete, leaving 539,000 square feet yet to develop, essentially doubling Swedish Issaquah in size by 2033.

According to the city of Issaquah, Swedish received an extension last September, allowing the temporary parking lot on the northeast corner of NE Blakely Drive and 8th Avenue NE to remain until December 2022. By December 2022, Swedish will need a master plan and a building permit for the remaining 539,000 square feet or remove the parking lot. According to Swedish Chief Executive and Highlands Council Trustee Chris Beaudoin, there is “nothing public to share at this time.

Bellevue College:

(Updated as of September 2021) Bellevue College owns the property along College Drive between Central Park and the Forest Ridge neighborhood. The 372,000-gross-square-foot parcel is zoned for institutional use, or could Bellevue College could sell to a developer that could construct up to 310 residential units.

Bellevue College Interim President Gary Locke said, “Unfortunately, I have nothing to report re[garding] our plans for the Issaquah Highlands property. We will, in the next few months, be taking a thorough review/analysis of the property, but nothing to report now.”

ISD School Siting

(Updated as of June 2018) In 2018, the Issaquah School District (ISD) considered a property on the western border of Issaquah Highlands, west of Swedish Hospital, for a new elementary school. After thorough site analysis (including geo-tech and arborist studies), ISD decided not to pursue the property for a school. In June 2018, ISD announced they would build a new elementary school on what’s referred to as the “Volpe property” on Issaquah Pine Lake Road, approximately two miles from Issaquah Highlands.

City Projects

City of Issaquah Capital Improvement Plan Projects

(Updated as of September 2021) The following are notable Capital Improvement Plan (CIP) development projects located in Issaquah Highlands (subject to change and does not represent a budget commitment):

South Spar Booster Pump Station

Construction in progress, estimated completion 2023. A drinking water booster pump station and approximately 8,000 linear feet of water transmission lines are under construction by the Issaquah Public Works Department. The project will provide redundant facilities to move drinking water to Issaquah Highlands, including to Swedish Hospital (which serves as a critical care facility), as well as to over 5,000 residents. As part of the project, a portion of the Issaquah-Preston Trail within the project site is closed until 2023; a detour travels through Olde Town. Find more information at

Highlands Sewer Main Capacity and Redundancy Project

Estimated completion 2023. The city will design and construct a redundant sewer main from Issaquah Highlands to the I-90 under-crossing to provide a redundant and larger capacity conveyance system that is safer and more reliable. Currently, one pipe conveys all sewage from Issaquah Highlands, running over a steep slope from 5th Avenue NE to the Issaquah Public Works Operations facility. The current system is more than 20 years old, designed when its planned use differed from its modern application. Today, the system experiences higher demands and higher flow than intended. Additionally, this system is the only sewer connection from Issaquah Highlands to the valley floor. A new redundant system would provide additional capacity and further protect critical facilities.

 Public Works Storage Site

Estimated completion 2024-2025. The city will design and construct storage facilities near the IHCA maintenance shop and Vista Community Gardens for Public Works Operations and Parks Maintenance equipment and supplies. The project increases productivity with trip time reductions and local storage of frequently-used materials.

Bike Skills Park

Estimated completion 2024. The city will locate, design, and construct a bike skills park, including a challenge course and pump track on Issaquah parkland. Initially conceived as a clustered set of features under the Bonneville Power Administration (BPA) powerlines in Central Park, this project will seek alternate locations through community engagement and consultation with project partner Evergreen Mountain Bike Alliance. Issaquah Highlands master developer Port Blakely dedicated funds to the city to develop a bike skills park, and the project has remained a community priority.

Central Park to Valley Trail via Issaquah-Preston Trail

Estimated completion 2027. Provide a trail connection from Central Park down to the Issaquah-Preston Trail, considered a needed non-motorized connection.

City Development Projects Beyond 2027

(Updated as of September 2021) The following are anticipated future year projects, not anticipated to begin until after 2027. Anticipated costs are rough estimates and will be refined further should the project timeline accelerate.

Aquatic Center

Issaquah location not identified in the city’s Capital Improvement Plan. Design and construct a large-scale pool facility with an estimated cost of $22,260,000. While the future facility’s Issaquah location is unknown, Issaquah Highlands residents have expressed a strong desire to have a community pool. Be sure to follow the work of city administration and the City Council during annual budget planning and annual reviews of the Capital Improvement Plans. Take advantage of public comment time during City Council agendas to share opinions and encourage action.

West Highlands City Park

Create a new public park for Issaquah residents and seek opportunities to connect this future park space to the valley floor and trail system.

Central Park Pad 4 Improvements

A $10 million investment to improve and activate existing undeveloped Pad 4 parkland and the Pad 1 parking area following the Central Park Master Site Development Plan, based on the community’s desire to create an open grass lawn area, picnic shelters, and an education area.

Lake Tradition to Central Park I-90 Crossing

This project would create an I-90 crossing from the Tradition Plateau to Central Park.

Central Park Traffic Signal and Mini Roundabout

Install a new traffic signal at the intersection of Central Park Lane NE and NE Park Drive. Construct a mini roundabout at the intersection of Central Park Lane NE and College Drive.

Park Drive Pedestrian Safety

Complete a design study to address additional pedestrian crossing issues along NE Park Drive between 17th Ave NE and the trail crossing east of Central Park Lane NE, including a potential second traffic signal at the Grand Ridge Elementary School driveway.

Central Park Booster Station Retrofit – Water Utility

This project consists of the design and construction of the Central Park Booster Station.
